Develop a video object tracking system using the following two methods: Condensation (particle filter) method Track the contour of an object (person, car, hand, etc.) in the first frame of a shot throughout the shot. Track the object in the form of coordinate of the contour polygon. Contour tracking demo animation 3D region growing method Track the specified region in the first frame of a shot throughout the shot. Track the object in the form of distance between each pixel in each frame and the specified area in the first frame. Specify the initial frame area. Expand the specified region in 3D using region growing method
